Please, Tell Me Does It Mean ..... ?

"In a test of a PAO vs. a mineral oil for seal compatibility, four seal materials were studied: acrylate, silicone, nitrile and fluoroelastomer. The seals were evaluated at the end of the test for changes in tensile strength, elongation, volume (seal swell), and hardness. The PAO performance fell within the specification limits for all four elastomers."

What does it mean in Bold ?

It means PAO failed (with four seals tested),
or,
PAO Passes All of them (OK with four seals)?

Passed. Fell within the limits.

So it means,
all oil of PAO base stock nowaday,
safe for all seal and gasket even for an old mobil ?

I guarantee it will. Pablo or Gary can link the info if they want to. They are PAID sponsors.
